Prior to version 10, hash indexes didn't perform well under concurrency, lacked write-ahead logging and thus were not safe in the face either of crashes or of replication, and were in various other ways second-class citizens. In PostgreSQL 10, this is largely fixed. @@ -18,12 +20,12 @@ While there's [always more that can be done][15], I feel that my colleagues and In closing, I'd like to thank Jeff Janes and Jesper Pedersen for their invaluable testing work, both related to this project and in general. Getting a project of this magnitude correct is not simple, and having persistent testers who are determined to break whatever can be broken is a great help. Others not already mentioned who deserve credit for testing, review, and general help of various sorts include Andreas Seltenreich, Dilip Kumar, Tushar Ahuja, Álvaro Herrera, Michael Paquier, Mark Kirkwood, Tom Lane, and Kyotaro Horiguchi. Thank you, and thanks as well to anyone whose work should have been mentioned here but which I have inadvertently omitted. ---- -via：https://rhaas.blogspot.jp/2017/09/postgresqls-hash-indexes-are-now-cool.html?showComment=1507079869582#c6521238465677174123 +--- +via：https://rhaas.blogspot.jp/2017/09/postgresqls-hash-indexes-are-now-cool.html?showComment=1507079869582#c6521238465677174123 -作者：[作者名][a] -译者：[译者ID](https://github.com/id) -校对：[校对者ID](https://github.com/id) +作者：[作者名][a] +译者：[译者ID](https://github.com/id) +校对：[校对者ID](https://github.com/id) 本文由[LCTT]（https://github.com/LCTT/TranslateProject）原创编译，[Linux中国]（https://linux.cn/）荣誉推出 @@ -42,4 +44,4 @@ via：https://rhaas.blogspot.jp/2017/09/postgresqls-hash-indexes-are-now-cool.ht [12]:https://www.postgresql.org/message-id/20170704105728.mwb72jebfmok2nm2@zip.com.au [13]:https://git.postgresql.org/gitweb/?p=postgresql.git;a=commitdiff;h=ff98a5e1e49de061600feb6b4de5ce0a22d386af [14]:https://git.postgresql.org/gitweb/?p=postgresql.git;a=commitdiff;h=ff98a5e1e49de061600feb6b4de5ce0a22d386af -[15]:https://www.postgresql.org/message-id/CA%2BTgmoax6DhnKsuE_gzY5qkvmPEok77JAP1h8wOTbf%2Bdg2Ycrw%40mail.gmail.com \ No newline at end of file +[15]:https://www.postgresql.org/message-id/CA%2BTgmoax6DhnKsuE_gzY5qkvmPEok77JAP1h8wOTbf%2Bdg2Ycrw%40mail.gmail.com
